Abstract

Dynamic renal scintigraphy (DRS) is widely used in the evaluation of hydronephrosis and hydroureter in infants and children. The aim of diagnostic imaging with high accuracy is to detect hydronephrotic kidneys at risk for loss of function, pain, hematuria, and urinary tract infection. The reliability of DRS depends on how the data are acquired and processed, as well as how the results are interpreted and used. This review highlights the basic concepts of standardized DRS and the pitfalls to avoid.
